Referring now more in detail arm extension assembly 20 made the present invention is shown to tubular handle having an elongated tubular portion 21, with an elongated tubular portion 22 assembled therein, with an adjustable related terminal brush-holder member 23 or 23' connected at one end thereof and having a fiat plate portion 24 extending therefrom. The tubular portion 22 being provided with a plurality of transverse holes through which a bolt 25 may extend and be clamped in position by wing nut 26. The tubular portion 20 may be made of two tubular members 27 and 28 having a rod 29 arranged therein and bolted together by bolts 30 and wing nuts 31. The tubular portion being assembled with member 28 and held in place by bolt 32 and wing nut 33. A rubber thimble type grip 34 is assembled upon the lower end of arm extension 20. A flexible wrist strap type handle 35 with free ends perforated is attached to tubular base member 27 by bolt 36. The upper end to the drawing, an in accordance with include a generally portion 37 of tubular portion 22 is flattened and provided centrally with a transverse bore 38. The brushholder member 23', clearly shown by FIGURES 13 and 14, consists of flat plate 24, a tubular receiving socket or channel portion 39, an angular extension 40 joined at 90 degrees with plate 24' and integral with tubular receiving socket or channel portion 39 and a flat clamping member 41 spaced from extension 40 and parallel therewith. The extension 40 and member 41 having bores 42 and 43 centrally arranged therewith and in axial alignment with each other. In FIGURE 1, the end portion 37 of portion 22 is clamped between said members 40 and 41 and clamped in angular position by bolt 44 and wing nut 45. The paint brush 46 is comprised of a large plurality of bristles 47 of any suitable character and held together to form a head 48 which is here shown as rectangular in cross section and provided with a cap 49, which fits over the head 48 snugly and is secured rigidly thereto by knurled means. The handle 50 of the brush is clamped by the cap 49 in longitudinal alignment with the bristles 47, said cap 49 and handle 50 each provided with aligned transverse bores 51 and 52 through which bolt 53 extends and parts clamped together, the bolt 53, removably arranged to extend through bore 54 centrally arranged in plate 24 as well as bores 51 and 52, all parts clamped rigidly by wing nut 55. By providing concave finger gripping areas 56 along one edge of the thimble grip the arm extension is easily raised, lowered, and laterally moved to apply paint or the like to a high corner area 57 shown in FIG- URE l by cross section representation.

In FIGURE 5 is illustrated a modified brush-holder 23. The brush-holder 23' differs from holder 23 only in that plate portion 24' projects from the opposite side of extension and in a direction opposite to that of portion 24. In FIGURE 5, the brush-holder 23 is shown with the fiat plate 24 clamped to the flattened upper end portion 37 of member 22 arranged vertically. The channel portion 39 or tubular receiving socket is arranged horizontally relative to plate 24' and holds the cylindrical handle 60 of brush 61 having bristles 62 and cap 63. The brush 61 with a round handle 60 is generally provided with cylindrical cap 63 and the bristles 62 secured in cylindrical manner. The bolt 44 and wing nut hold the round handle rigidly within the channel 39 when in use but are easily removable.

As shown by FIGURES 6 and 7 the brush-holder 23 has an arm extension 37 shown horizontally for convenience. The brush 65 here shown has a long flat handle 66, a body 67 of rectangular cross section, bristles 68 and secured by cap 69. The body 67 and cap 69 have aligned bores formed therein, and a bolt 70 extends through openings 42 and 43 of holder 23 clamping flat extension 37 between members 40 and 41, and further extends through the aligned bores in body 67 and cap 69; and all said parts being clamped together by wing nut 71. The angle plate 24 is left for securing a scraper or the like thereto.

The invention is further shown by FIGURES 8, 9 and 12 with modified attachments. As is well known, before a surface is painted, it should be scraped, sanded, and cleaned with a sponge to wash the area satisfactorily. To attach the scraper, the sander, and the like, it, is often desirable to use a telescopic article, or arm extension, provided with a transverse aligned bores, bolts, wing nuts and ferrules assembled with the various sections. The telescopic article shown by FIGURE 8 has the common sections 27, 28, reinforcing member 29, bolt 30, nuts 31, thimble 34, strap 35, bolt 36, finger grips 56 and the like. The uppermost extension 73 has a tubular base portion 74, and with a semi-circular top portion 75 with convex outer surface 76 and a fiat supporting surface 77. An angle plate 78 is attached to said surface 77 by bolt 79 and wing nut 80; the surface 77 being provided with a bore for the reception of the shank of the carriage bolt 79 which passes through a bore in the angle plate; the wing portion 82 thereof is integral with the base of angle plate 78 and has a longitudinal slot 83 extending therethrough. A scraper, or a sander, or sponge can be attached to the wing portion 82 as required. It is clearly shown that the base portion 74 is provided with a plurality of transverse bolt holes 85, whereby the section 28 and section 73 can be adjusted in position relative to each other and locked against longitudinal movement. The telescoping of one section within another provides strengthening means for the tool.

The invention shown by FIGURE 9 is the same as described above except that the sections are provided r with oval portions, for example the section 86 is telescoped within section 87 and bolted by bolt 88 and nut 89. Section 87 is provided with oval section 90, see FIGURE 11, to strengthen the same. The uppermost extension is formed of wood, having a cylindrical base portion 91 and fiat top portion 92 which is rectangular in cross section. The cylindrical bottom portion telescopes within the uppermost end of section 87 and fits in socket 93 above oval section 94 and secured therein by bolt 95 and nut 96. The fiat top portion 92 is provided with a bore 97 through which a bolt may pass to secure a brush, a scraper, a sander, a sponge or the like for use around electrical connections; a complete metal tool of metal sections may provide a hazard of fire or the like.

The invention shown by FIGURE 12 is a slight modification thereof, the lower most section 27 has a telescoping inner cylindrical tube 98 sliding therein. The tube 98 is provided with a plurality of holes 99 spaced apart longitudinally there along whereby bolt 30 and nut 31 can rigidly lock the same together to provide a two piece tool to support a brush or the like.

The invention is further shown in a modified form by FIGURE 16, where the metal tubular section 28 has a fiat wooden member 100 arranged slidably therein, the wooden member 100 having a plurality of holes 101 arranged transversely therethrough to receive the bolt 103 and become locked in position by the wing nut 104. The flat free end 105 thereof is arranged between members 40 and 41 of holder 23 while the angle plate member 78 has its base plate bolted to the surface of plate 41 allowing the wing portion 82 to extend outwardly therefrom for supporting a scraper or sander or the like.

It is clearly seen that adjustment of the distance of the brush or scraper from the body, or handle portion of the device is attained by sliding the various sections or parts toward or away from the base portion and thereafter, lock them in place by means of bolts and wing nuts as shown by the drawings.

It is well known that painters must remove rust, old loose paint, paint blisters etc., especially on chimneys, water tanks, gas tanks, flag poles, bridges and ships. It is necessary to have an arm extension to support brushes, scrapers and sanders attached to angle plates or metal grippers as disclosed in the above application.

It is herein disclosed that an adjustable brush handle, or combined brush, scraped and sander handle has been provided in which a multitude of different adjustments of the several parts are most easily attained, and in which interchange of brushes, scrapers, sanders or other implements is most quickly effected. The wrist strap 35 is to represent any type means to prevent the painter dropping the arm extension.

Further, it is to he noted that when the device is not in use the handle and the extensions may be telescoped or slipped apart to thus materially reduce the overall dimensions and permit the device to be stored in a small space.

It is to be noted further that the device is of extreme simplicity, is rugged in construction and may be cheaply and readily produced.

It is again to be noted that the term brush used in the description and claims is to be interpreted in a general sense or illustrative sense rather than in a limited sense, as it has been employed merely to avoid needless repetition in the description and claims.
